没有这样的东西作为波斯 DateTime 。 DateTime 值始终是公历日历值，没有特定格式。设置格式时（通常通过调用 ToString ），可以确定其格式-如果您使用的文化使用非格里高利历法，它将转换原始值

There's no such thing as "a Persian DateTime". A DateTime value is always a Gregorian calendar value, with no specific formatting. When you format it (usually by calling ToString) you can determine how it's formatted - and if you use a culture which uses a non-Gregorian calendar, it will convert the original value into that calendar.

因此，例如，如果您想解析波斯用户的输入，然后将其转换为英语用户可以理解的等效日期，则可以使用：

So for example, if you wanted to parse input from a Persian user and then convert that to the equivalent date that an English user would understand, you could use:

DateTime date = DateTime.Parse(text, persianCulture);
string englishText = date.ToString(englishCulture);
